Evaluation and Selection of Cement Suppliers under the Background of New and Old Driving Energy Conversion in China

Accompanied by the concept of supply-side structural reform and conversion new old driving energy to create a round economic development in China, cement supplier evaluation selection are increasingly crucial for concrete production plants, ensuring not only raw material supply with high quality at reasonable price but also sustainable long-term cooperation suppliers. Given limitations existing approaches, this study proposes framework based on combination improved FAHP-CRITIC method VIKOR method. We first develop index system under background conversion, including eight first-level indicators twenty-one second-level indicators. The proposed model then uses triangular fuzzy numbers AHP (TFN-AHP) CRITIC calculate subjective objective weights replacing coefficient variation standard deviation, ideal solution-based determine their weights, combines comprehensive values candidate After that, approach is applied evaluate select ten suppliers results compared analyzed those using traditional comparison show that strategy can be scientific reliable, helping managers make right decision China.
